Symptom:
Initial replication setup is unable to complete.

Conditions:
- Encountered on CAD 8.5(4) ES7
- Initial replication setup fails to complete due to LDAP failure
- extra file is located in primary CAD server's database folder, other than what CAD creates itself during install
- in our case, "repl.log" was present in the primary server's database server, which was manually created, and prevented replication from working
- during replication setup, a type of DB check goes through and verifies the number of files between primary and secondary servers
- If there is a mismatch, it will fail.
